Specification of Letters Patent.

Patented Dec. 24, 1912.

Application filed December It, 1810. Serial No. 696,773.

To all whom it may concern:

Be it known that I, Mrnnann D. Onos, a citizen of the United States and a resident of Cheboygan, county of lheboygan, and State of Michigan, have invented a new and useful Improvement in Stakes for Logging- Cars and the Like, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contem lated applying that principle, so as to istinguis it from other inventions.

The improved construction of stake, or do which constitutes my present invention, is esigned primarily for use upon logging cars or like vehicles, as indicated, but may be obviously em loyed in other similar connections as nee not be explained in detail.

The function of the device is to retain 10 or equivalent materials, upon the bunks o the vehicle and the object of the improvement is to provide a device of this kind which while thus retaining the logs securely in (place when desired, is adapted readily an easily to release the same and allow them to be rolled off such bunks.

To the accomplishment of this and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constitutin however, but one of various mechanical orms in which the principle of the invention may be used.

In said annexed drawingz-Figure 1 is an end elevational view 0 a logging car with its bunk provided with log-retaining stakes, or doi s, embodying my present improvements; ig. 2 is a side elevational view of one such dog on an enlarged scale; and Fig. 8 is a similar end elevation of the same.

The loggin car, of which, for obvious reasons, on K t e one truck 1 appears in the drawing, (t e view being an en elevation), is of the usual construction, as is also the floor or deck upon which rest the bunks 2 that are of present interest. On a flat car, four of these bunks are ordinarily provided, two for each tier of logs, it being customary to use such bunks on top of the fiat car so as to hold the 10 u from the floor of the car, as also to sue le hem to be more readily rolled off. In the present improved construction this bunk, or at least the upper portion thereof, consists of a piece of standard railroad iron or rail as indicated in Fig. 3. The dogs or stakes 3, of which two are provided to each bunk, are formed so as to engage the ball and web of the rail, being adapte to grip such ball when pressure is brought to bear against the upper end of the stake in a direction longitudinally of the rail. Of the two stakes the one, on what may be termed the farther side of this car, is held against outward movement along the rail by a pin 4, or like retainin member fitted in a ole in the rails web. he other stake is formed with a In 5, through the hole in which a bolt 6 is inserted in order to form means of attachment for a chain 7 extendin across the car and secured to the car y at such farther side. This chain is sufiiciently long to permit the stake in question to slip entirely off the rail, but may be held taut, with such stake occupying an intermediate position on the rail, as i lustrated for example in Fig. 1, b means of a bifurcated jaw 8 on the cars arther side. This jaw is conveniently made out of a bent strap of iron, in which a slot is cut of sufiicient width to let a link of the chain be inserted edgewise.

Owing to the location of the lug 5, viz., in that portion of the stakes body that depends below the ball of the rail, the chain restrains the movement of the stake to which the latter would otherwise be sub'ected in the loaded condition of the car; or the pull of the chain being below the rail-ball while the pressure of the logs is against the portion of the stake rejecting above, such stake is in effect locks in place. With such movable stake thus held, the bunk is obviously ada ted for the reception and retention of the 0 which it is designed to carr When it is esired, however, to unload t e logs it becomes necessary to remove one of the stakes, in the present construction, the one just described as being removably mounted on the rail. When this is desired, the chain is disenga ed from the jaw 8 to which it is temporari y attached, and then by lightly tapping upon the stake, by means of a pike po e or bar such stake ma be knocked out and the 10 allowed to r0 1 oil the rail. In practice 0 course the removable stake will thus be dislodged by an operator positioned on the'oflposite side of the car.'(termed above the fart er side), so as. nottofendanger the operator, who might otherwisejbe crushed;

have to" be made in t eform of t a device 8 for securing the same at th 'farther side of the car.

Other modes of agglying the fn'inciple of my invention may em loye instead of the one explained, change ein made as regards the mechanism herein isclosed rovided the means stated by any of the fol owing claims, or the equivalent of such stated means be employed. 7

I therefore particularly point out and distinctly claim as my invention:-

1. In a device of the character described the combination of a rail forming a bunker; a stake slidable upon said rail, said stake being formed so as to completely inclose the offsaid rail; and extensible means con- .nected with the lower portion of saids'take 'andhdapted to causev said. stake to engage the ball of said rail with a rotative pressure, vthereby retaining. the same against movementalong said rail- 2.,Inadevice of the character described, the combination of a rail forming a bunker;

a stake slidable upon said rail, said stake bein? formed so as to completely inclose the bal and web of said real; and extensible means connected with a lug on the web gripping portion of said stake and adapted to cause said stake to engage the ball of said rail with a rotative pressure, thereby retaining the same against movement a ong the and rail.

Signed my me this 3rd day of December,
